Subject: [PATCH] Bluetooth: btbcm: allow btbcm_read_verbose_config to fail on
 | 
			
		||||
 Apple
 | 
			
		||||
 | 
			
		||||
Commit 1c8ba6d013 moved around the setup code for broadcomm chips,
 | 
			
		||||
and also added btbcm_read_verbose_config() to read extra information
 | 
			
		||||
about the hardware.  It's returning errors on some macbooks:
 | 
			
		||||
 | 
			
		||||
Bluetooth: hci0: BCM: Read verbose config info failed (-16)
 | 
			
		||||
 | 
			
		||||
Which makes us error out of the setup function.  Since this
 | 
			
		||||
probe isn't critical to operate the chip, this patch just changes
 | 
			
		||||
things to carry on when it fails.

Subject: [PATCH 1/2] block: loop: convert to per-device workqueue
 | 
			
		||||
 | 
			
		||||
Documentation/workqueue.txt:
 | 
			
		||||
	If there is dependency among multiple work items used
 | 
			
		||||
	during memory reclaim, they should be queued to separate
 | 
			
		||||
	wq each with WQ_MEM_RECLAIM.
 | 
			
		||||
 | 
			
		||||
Loop devices can be stacked, so we have to convert to per-device
 | 
			
		||||
workqueue. One example is Fedora live CD.

Subject: [PATCH 2/2] block: loop: avoiding too many pending per work I/O
 | 
			
		||||
 | 
			
		||||
If there are too many pending per work I/O, too many
 | 
			
		||||
high priority work thread can be generated so that
 | 
			
		||||
system performance can be effected.
 | 
			
		||||
 | 
			
		||||
This patch limits the max_active parameter of workqueue as 16.
 | 
			
		||||
 | 
			
		||||
This patch fixes Fedora 22 live booting performance
 | 
			
		||||
regression when it is booted from squashfs over dm
 | 
			
		||||
based on loop, and looks the following reasons are
 | 
			
		||||
related with the problem:
 | 
			
		||||
 | 
			
		||||
- not like other filesyststems(such as ext4), squashfs
 | 
			
		||||
is a bit special, and I observed that increasing I/O jobs
 | 
			
		||||
to access file in squashfs only improve I/O performance a
 | 
			
		||||
little, but it can make big difference for ext4
 | 
			
		||||
 | 
			
		||||
- nested loop: both squashfs.img and ext3fs.img are mounted
 | 
			
		||||
as loop block, and ext3fs.img is inside the squashfs
 | 
			
		||||
 | 
			
		||||
- during booting, lots of tasks may run concurrently
 | 
			
		||||

Subject: [PATCH] Enable loading of bitmaps for dm-md-raid1.
 | 
			
		||||
 | 
			
		||||
This is also a temporary hack to systems with junk in the rest
 | 
			
		||||
of the bitmap super (instead of zeroes) to boot. This is done by
 | 
			
		||||
checking mddev->sync_super (which is exclusively set by dm-raid)
 | 
			
		||||
is null.
 | 
			
		||||
 | 
			
		||||
These changes also include zeroing of most bitmap pages while
 | 
			
		||||
allocating so we are sure that the junk is not coming from memory.
